AIR COOLING AND DEHYDR'ATING' DEVICE.

Application filed. July 25,

This invention relates to devices for cooling and for partiallydehydrating the air contained within enclosures.

One of the objects of the invention is the provision of new and improvedmeans for cooling the air contained in rooms, halls, buildings and thelike.

Another object of the invention. is the provision of new and improvedbeans for partially dehydrating the air contained in enclosures in whichthe device is employedi A further object of the invention is theprovision of new and improved means for reducing the ten'iperaturc inenclosures and more particularly in enclosures occupied by human beings,as dwellings theaters, schools, churches, stores, shops and the like,and sin rultaneously ren'ioving a portion of the moisture contained insaid air to thereby render the air in said enclosures more comfortablefor human habitation.

Other objects of the invention are the pro vision of a new and improveddevice for cooling and partially dehydrating air, that is simple inconstruction, cheap to manutacture, easily assembled, eflicientinoperation, and that is not likely to become broken or get out of order.

Other and further objects and advantages of the invention will appearfrom the following description takenin connection with the accompanyingdrawings, in which Fig. 1 is a perspective view of the device;

Fig. 2 is a longitudinal section thereof; and

Fig. 3 is a section on line 33 of Fig. 2.

On the drawing the reference character designates a box or containerwhich may be of any desirable form and composed of any suitablematerial. In the form of the device selected to illustrate oneembodimentof the invention, the container 10 is rectangular in form andcomposed oi sheet metal. The container is provided with an air passagethrough which air may be caused to move. As shown, the end walls 11 and1:2

iii

of the container are provided with openings 18 and lt respectively forthis purpose. The upper wall 15 of the container may form a lid orclosure hinged asat 16. The closure 15 is preferably provided with ahandle 17 whereby the same may be lifted to permit access to theinterior of the container.

It is a well known fact that warm humid air is more uncomfortable thandry air at the same tempe 'ature. 111 other words, ha-

mid air in warm weather will appear to be or feel several degrees,warmer than dry air at the same temperature, due to the fact that withdry air the skin is cooled by the more rapid evaporation ofperspiration. It is also a; matter of common knowledge that the airscapacity for moisture decreases as the temperature decreases. Suitablemeans are provided tor taking advantage ot'theseprinciples, for not onlylowering the temper'-:

ature but also partially dehydrating or removing a portion of themoisture from the air whereby the same will" appear to be at a lowertemperature than it actually is. As:

may be employed, that shown being a lump of ice 19 which is placed insaid receptacle. The receptacle is comparatively shallow and is lesswidth than the container. Suitable means, as the supporting brackets21'and 22 are provided for supporting the receptacle 1n spaced'relationto the top, bottom and: side walls of the container whereby air directedthrough the receptacle by any suitable means as the fan 23 willcirculate about the receptacle.

The receptacle is supported so that the upper edge of its front wall 25will extend across the opening 13. The front wall 25 is arranged at anangle to the bottom wall whereby the same will deflect a portion of theair beneath the receptacle. An impertorate bafile 26 is provided whichis adapted to extend upwardly and to either side in engagement with thetop and side walls of the container to form a deflector in alinementwith the rear wall 30 of the receptacle whereby the air entering theopening 13 above the front .wall 25 will come in contact with thecooling agent and will be compelled to flow over the sides of thereceptacle and mingle with the air entering the lower portion of theopening 13. thus assisting in cooling and causing the same to depositits moisture on the condens ing surfaces of the receptacle.

In order to deflect the air downward on the cooling agent a suitabledeflector 27 may he provided. The deflector 27 is preterably hinged asby a detachable hinge 28 whereby the same will automatically adjustitself to the size of the cooling agent. It ice be employed, the rearend of the de liector will. rest on the ice and will move downward asthe ice melts The baffle 26 may, if desired he provided with flanges 29having slots therein for engaging headed pins 31 on the side walls ofthe container, tor positioning the baflie.

In the operation of the device a cooling agent as ice is placed withinthe receptacle and a current of air is caused to flow through thecontainer. The air is directed onto the ice and a portion of its heat isabsorbed by the ice, thus melting the ice and torming' ice water 33 inthe receptacle, which cools the walls of the receptacle to such anextent that the air deflected downward by the front wall 25 and comingin contact with the bottom and side walls of the receptacle will becomechilled and deposit its moisture. That portion oi the air currentflowing on to the ice will flow over the sides of the receptacle andmingling with the adjacent air will assist in cooling the same. The coolair will pass beneath the battle formed by the rear wall of thereceptacle and will flow upward and out into the room or other enclosurethrough the opening 14 as indicated by the arrows in Fig. 2. The air inthe room is not only cooled and partially dehydrated but is caused to becontinually circulated by the operation of the fan.

While I have shown a tan for forcing air through the container and haveshown a receptacle containing ice within the container, it is understoodthat this disclosure is by way of example only as any suitable means maybe employed for causing the air to flow through said container and anysuit- 1 able arrangement of condensing surfaces and means for ciiolingg;the same may be employed without departing from the spirit ot theinvention, or scope of the appended claims.

I claim as my invention:

1. In combination, a casing, a container adapted to contain a coolingagent. supported within said container. means for directing a current ot air over and about said container. and a battle plate at the rear oisaid container engaging the side walls and top of said casing, saidhaiile plate terminating short of the bottom wall to form an air passagebeneath the same.

2. In combination, a casing" having, openings in its front and rearwalls a container in said casing spaced from the side Walls thereof,adapted to contain a refrigerant, means for supporting said container inspaced relation to the rear wall of said c2 .3- inc" and opposite anopening in said front wall, whereby air enteringsaid opening will passover said container. and an impert'oratc battle extending above saidcontainer at the rear portion thereot tor reflecting: the air enteringsaid casinp above said container, back over said refrigerant.

3. In combination. a casing having openinns in its front and rear walls,a refrigerantcontainer, means for supporting said container in spacedrelation to the bottom and rear end walls of said casing, means fordirecting aportion oi the air entering said casing above said container,a battle extending above said container on the rear portion thercoi, anda deflector hinged at the forward portion of said inn and having; itsrear end adapted to rest. on the refrigerant in the container fordotlectingr air entering said casing about said refrigerant.
